20.500.12556/RUL-167370 Manganove spojine s pirazinojsko kislino Manganese compounds with pyrazinoic acid Izvedli smo reakcije med mangovim(II) kloridom dihidratom, manganovim(III) acetatom dihidratom in manganovim(II) sulfatom monohidratom s pirazinojsko kislino v topilih: metanol, etanol in acetonitril. Reakcije so potekale pri sobni temperaturi ali pa na oljni kopeli pri višji temperaturi. Kristalizacija je potekla na zraku ali v zaprtem sistemu za kristalizacijo pri nižjem tlaku. Z manganovim(II) kloridom, sulfatom in pirazinojsko kislino nam je uspelo sintetizirati dva kompleksa, [MnCl$_2$(pyzaH)$_2$] in [MnCl$_2$(pyzaH)$_2$]n·2nH$_2$O. Za potek reakcije med manganovim sulfatom in pirazinojsko kislino je bilo potrebno dodati koncentrirano klorovodikovo kislino. Za potrditev nastanka novih kompleksov smo uporabili analizne metode: IR spektroskopija, CHN elementna analiza, termična analiza, rentgenska praškovna analiza in rentgenska strukturna analiza. We carried out reactions between manganese(II) chloride dihydrate, manganese(III) acetate dihydrate and manganese(II) sulfate monohydrate with pyrazinoic acid in solvents: methanol, ethanol and acetonitrile. The reactions were carried out at room temperature or in an oil bath at a higher temperature. Crystallization was carried out in air or in a closed crystallization system at a lower pressure. With manganese(II) chloride and sulfate, we managed to synthesize two complexes [MnCl$_2$(pyzaH)$_2$] and [MnCl$_2$(pyzaH)$_2$]n·2nH$_2$O. For the reaction of manganese sulfate and pyrazinoic acid it was necessary to add concentrated hydrochloric acid. To confirm the formation of new complexes, we used analytical methods: IR spectroscopy, CHN elemental analysis, thermal analysis, X-ray powder analysis and X-ray structural analysis. mangan pirazinojska kislina koordinacijske spojine manganese pyrazinoic acid coordination compounds true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-02-18 13:30:00 2025-02-18 13:30:03 2025-02-28 12:05:50 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 24247 227668227 Pocervina_Ziga_-_Manganove_spojine_s_pirazinojsko_kislino.pdf Pocervina_Ziga_-_Manganove_spojine_s_pirazinojsko_kislino.pdf 1 39DFD7E52AF7AB3DB6EADB9F29303223 aaa1f697c526a1ea6ba20400ececfdf10d0f98dfe2adbba52be246af5bcff26e 30419a22-edf3-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199749 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
